To alt trimm 'if may romfcrn.: l

Bc it known that I, Hartman lNGRAnAi/r, of' Naples, in the county ofOntario and State ot' New York, have invented a new and ImprovedCultivator;` and I do hereby declare the following 'to be a full, clear,and exact description of the construction and operation of the same,reference being had to the accompanying drawings, and to the letters of4reference marked thereon, making a part of this` speciti4 cation, 1nwhich- Figure lis a top orplan view ot' my improved:

cnltivator, showing the arrangement. of' the ,frame and the slottedknee-braces for ad j nstin g` the thills or shafts, whichwillhereinafterbedescribed. d'icated by'theiine .r y in Fig. l, in order toshow more clearljr the manner of adjusting the thills by theknee-braces.

Like letters indicate corresponding parts in all figures of thedrawings.

My improved cultivator is designed to be an improvemcntin someparticulars on that which -I patented in December 27, 1864. In that theframe is made in the shape of the letter LT, or

a beam is attached at one end `to the' center (it` a transverse one,approximating to a lettero't' that shape. In the transverse beam justmen' ticned there are attached two cultivating-teeth, which beam landteeth are placed atthe forward frontend of the center beam, and at!tached at the rear end t' this beam isasingle cultivating-tooth,ordinary handles beingused, such as are usedom plows, and attached tonear the rear end of the center beam, and secured firmly thereto by aAbrace made in thcshape'cf the frame above described, the thills orshafts being adjusted by their connection with mo` v v able eccentricangeshaped wedges' placed on the ends ofthe cross-beam. 4The arrangement`of the frame and the adjustment of the thills 'moved to the frontendofthe center beam, byv4 which change the soil thrown oftfromthe sidesFig. 2 is a section of theframeasinofthe fionttooth whfenfthemachineis'inmo tion is caught or taken up bythe advancing rear teeth,whicln'in addition to the soil furrowed up by them, presses the quantitythsid creased toria-rd the rows, thereby aiding materially in'theibrination of the jhills;"secondly, thc-substitntioii ot'kne-braces-in place of eccentric flange-'shaped Wedges for the `adjust-` ment ofthe thills7 they-` being-much simpler in their construction and not soapli-to' `get'ont ot' order, and more .conveniently applled in theadjustingofihe. thi1ls.

To enable any onesklled inthe art to make i and use my improvedcnltivator, Lwillpr'oceed to describe its coustructionand operation,

The frame herein referred to'is of'the utmost lightness a'ndsimplicitymits construct-ion, liel ingdevoid of that cumbersome weightandcomplication of parts peculiar to'mostofthose noiv in use, andtherebyrendering` it acceptable tot` alarge class ot' farmers, the smallquantity .off material used enablingthem to bebni'ltwi-th but comparntive'ly little trou ble. l have a tran sverse beam, A, bol tedon the'top and at the end of a beam, a, placed in the center the re to.

This beamprojects forward, and may 'be termed the i center forward beam.Bolted at thefront end and on the vtop thereof is another transl versebeam, B, but of aless width than the other. V'This beam is` intended to.support the knee-braces for adjusting the .thills,of which l p willspeak hereinafter.

The center beam in. theA patented one, which Vmay be termed in thatfthe-rear centerbeam,` is bolted on the top yoffv the transverse beamfatthe fro-nt instcad'ofnnder, as just abovedef scribed. The reason for thechange is, thev thickness ofthe center beamzbeingfnnder nstead of ontop, as in. the other, obviatesthe' lengthening ofthe shank of theforward tooth,

which would be required `Were the center beam placed otherwise to theextent of .the thickness of the'b'eam, and, besides," the properelevation Vof the-front or-forward part otthe machine is preserved, andthe thills therewithlreptto their proper position by rthe thicknessotthebeam across on-tlie4 top of the center one..

Tqmakeit more fully nDderstOod, in my pat-` len-ted'cultivator there is`only-*one tranverse beam, which is at .the frontend of vthe machine.-In this it is placed .at the. rearf or back 'endof` the machine furthepurpose as herein ,ex`

plaine'd, and anitciditional transverse beam is placed at the frontE forsupporting the kneebraces for .regulating the thills, the center beamretaining the same position as before, except, inchan ging the beams, itprojects forward instead of in the rear.

The-knee braces C G, to which reference has i been made, are bolted tothe top uof the front transverse. beam, (seen in Fig. 1,) irst beingplaced well against the inside ot' the thills D, which latter aresecured to thetopot' the rear tranverse beam by two bolts in each.4 Ineach knee-brace thereis a slot, c, (seen `-in Fig. 3,) through which andthe thills passes a bolt having screw-threads near the outer ends, withv nuts of'a suitable size to rit them. The inner' end of the bolt is'headed to prevent slipping through the slots. Theobject of this arr-angenientis to obviale the necessity, o'r rather inconlvenience, ot'lengthening' or shortening the llame-straps 'to which thethills areconnected,

` arising from the use ot' a high orlow horse, or. .p from other causes,such as will occasion the handlingof'the straps to regulate the thillsby simply loosening the nuts on the bolts and adj Listing the thillstothe position desired, and then tightening them, the saw-cut edges d(seen at letter E) ot' the braces against the thills, when tightlyscrewed, preventing their slipping up or down.

Considerable trouble is experienced frequently inadjusting theAhama-straps, in order made of east-iron, the shape of which isrepresentetlina. side view shown at letter E.

Having thus fully 'described my invention, whatI-claim therein as new,and desire to secure by Letters Patent,-is.

The transverse beams A andv B and center forward beam,ja', in connectionwith the kneebraces C, as constructed and arrtniged, substantially inthe manner and' for the purpose set forth.
